Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in the figure, the model structure for printing the brake caliper bracket casting template comprises a sprue cup 1 and at least three casting models 10, wherein the bottom of the sprue cup 1 is connected with a cross gate 2, the bottom of the cross gate 2 is connected with at least two vertical gates 5, all the vertical gates 5 are connected with the cross gate 2 through a water inlet sheet I3,
the casting model 10 is divided into at least three layers, the casting model 10 is located between two adjacent vertical pouring channels 5, the top of each casting model 10 is connected with two risers 7, the two risers 7 are respectively located right above the two mounting holes of the casting model 10, and the side parts of the two risers 7 are respectively connected with the vertical pouring channels 5 on the two sides through water inlet pieces 6.
